7 Claims. (01. 1' '21)' This is a divisional application of anapplication for patent filed in my name on October 1932, Serial Number639,221.

This invention relates to the art of manufacturing shoes, and hasspecial reference to a machine for inserting fasteners and. forming theheel area of a sole.

The object of the invention is to apply and permanently secure, in asingle operation, a pronged and apertured eared plate to the preparedheel seat of a shoe and simultaneously therewith shaping the heel seatand holding it from spreading while under pressure. 1

As more fully described hereinafter, I attain these and other objectsand results by a series of steps, or operations carried out on a machinecapable of carrying out all of the operations necessary by a singleoperator.

The novel machine herein described comprises mechanism for providing a.prepared heel seat with a heel attaching plate under pressure andsimultaneously therewith shaping, or preparing the heel seat for theapplication of a heel thereto while held against spreading.

More specifically, but briefly defined, the machine or apparatuscomprises a mechanism including means for securing heel attaching platesto lasted shoes and means for finally shaping the heel seat, and meansfor gauging the counter to prevent spreading of the counter whileunderpressure.

The various operating parts, by which the several stages in the securing.of heel attaching plates to shoes is accomplished, are simple inconstruction and operation and the machine has all of its operatingparts and mechanisms combined andarr-anged in compact form, the variousparts, however, being removable and adjustable so that the machine, as awhole, possesses the widest range of adaptability for securing heelattaching plates to shoes of various shapes and sizes.

The present invention maybe used in connection with the devicesdisclosed in the pending application of August G. Eichhorn, SerialNumber 603,995,filedApril'8, 1932." J

The invention will be more readily understood by 'reference to theaccompanying drawings, forming part of this specification.

vInthe drawings, B designates, generally, the 7 machine which appliesand permanently secures the heel attaching plate to the heel seat of theshoe. H r

The machine, as shown, is positioned on a table D provided withsupporting legs E, or, if desired, the machine may be secured to thecustomary work bench used in shoe factories.

The machine, or apparatus for carrying out the invention is shown in'oneform as consisting of a suitable stand embodying a base I, an upright 2having a laterally directed arm 3 disposed a suitable distance above thebase I and a plunger device. The plunger device embodies a suitablecylinder 4 supported by the arm 3 of its respective unit, a piston 5workable therein, and a non-rotatable'ram, or rod 6 depending from thepiston and directed through the bottom of the cylinder to a suitablepoint therebelow.

The plunger is provided at its lower end with a suitable removable head,designated 12 and held in position on the lower end of the plunger or 5within the cylinder is moved upwardly by the action of a suitablespring 1. The piston is responsive to fluid pressure for moving the ramassociated therewith downwardly, and the piston of a suitable conduit 9and the fluid pressure to ,the cylinder is. controlled by asuitabletwoiway valve l0.

Y When the valve handle ll of the valve is in one'position, the valve isclosed to the passage ,ram by suitable fastening means 6'. The pistontoward and away from each other.

duit l2, and when the valve handle of the valve is moved to its outerposition the fluid pressure within the cylinder is exhausted, as at l3,which allows the piston within the cylinder to be raised by the actionof the spring.

The means for supporting a lasted shoe on the machine will now bedescribed.

A pair of suitable guides [4 are ijxed on the base I of the machine. Asuitable lasted shoe support I5 is mounted for sliding movement on thebase I between the guides I4 so that the support can be moved toward andaway from the upright 2. When operatively positioned, the support I 5 isdisposed below the plunger 6, as shown in Figs. 1 and 2. The support I5is provided with a suitable swivelly mounted head [6 having a recess I!open at its forward end. The lower surface of the head I6 is suitablyconcaved, or longitudinally and transversely curved, as at l8, and theupper surface or" the support I5 is suitably conve'xed, orlongitudinally and transversely curved, as at IS. The support isprovided with a suitable opening 20. The head 16 is held on the support[5 by means of a depending pin 2| insertable through the opening 20. Asuitable spring 22 encircles the pin and is interposed be-' tween theapertured top of the support [5 and a stop 23 carried by the pin. Therecess I? of the head I6 is adapted to receive a part 24 of a shoe last'25 to be supported by the recessed he'a'd l6.

A shoe, designated generally as F, to be heeled, is supported by thelast 25, as clearly illustrated. The heel seat of the shoe F isdesignated 1.

The gauge mechanism for locating the shoe counter and the heel seat of ashoe in proper position relative to the plunger, Orr-am of the machine,includes a suitable supporting member 26 adapted to be mounted forvertical movement between suitable guides 21 on the upright 2 of saidmachine unit. Mounted for horizontal adjustment on the support 26 andlocked thereon in any of various adjusted positions by suitable lockingmeans 28, is a suitable plate 29, having a slot 30.

A screw threaded end 3| of the locking means 28, Passes through theplate 'slot 30 and is 're- 'c'eivable in a screw threaded opening 32 inthe support 26. The forward'end'of'the plate is provided with a suitablehead 33,as shown in Fig.

6, and the'head is provided with a suitably shaped transverse recess'34. Associated with the head '33 are a pair of suitablegauge arms 35,the rear endsfof which are provided with suitable heads 36 shaped toconform to the plate head recess 34,

amend heads are so shaped as to prevent movement of the gaugearm headsin any direction but The gauge arms are moved toward and away from eachother by means of a stem 31 having right and left'handed screw threads38 and 39. The screw reduced in diameter, as at 42, and this non-screwthreaded section'of the screw stem 3'l is held in a suitable bearing 43'to prevent longitudinal movement of the screw stem 31 relative to'thegauge arm heads 33.

The gauge arms 35 are shaped to conform to the counter of a shoe'a'ndthe inner sidefaces thereof are beveled as at 44 between thei'nner"endof the heads 36. The gauge arms are'adapted 2,028,382 of fluidpressure therethrough from a feed conto straddle the shoe counter belowthe heel seat of the shoe. The shoe counter is designated f in Fig. 6.When the screw stem is turned clockwise, the gauge arms 35 are movedaway from each other and when turned anticlockwise, the gauge arms aremoved toward each other. Thus, the gauge device can be adjusted toaccommodate any size of shoe counter.

The gauge device serves to locate the desired position of the heel seatof the shoe relative to the plunger of the machine, and to preventbulging or spreading of the shoe counter when pressure is applied to theheel seat I, as will be fully described hereinafter. The machineincludes a suitable foot pedal 45, pivoted as at 46, and the foot pedal45 is connected with the guided support 26 through the medium of asuitable connection 41, which connection is encircled by means ofsuitable coiled expansion spring 48 disposed below the guided support 26and the base I The spring 48 normally holds thegauge mechanism in itsuppermost position relative to the lasted shoe support, as shown indotted lines in Figs. 4 and 6.

Plate carrying tool and operation of machine.

The machine is adapted to apply andsecure a heel seat plate H shown insectional view in Fig. 3, to the heel seat of the lasted-shoe and; tofinally shape or form the heel seat for thefapplication of a heelthereto. The means for performing this operation comprises theplateholder b removably secured to the lower end of the plunger 6 of,the machine. The plate holder b is provided with a suitable concavedlower face 54 and a plane surface '55 .ior finally shaping, -or formingthe heel seats simultaneously with the applying of the heel plate to theheel seat of the shoe. The holder 2), as shown in Figs. 2 and 3, isprovided with a pair of suitable transverse slotted recesses designated'56 and '5? into which is inserted the apertured ears 58 and 56,respectively, of the heel seatiplate H and which ears arefrictionally,but removably held in said slotted recesses 55 and'fil by two balls 86and El, respectively against which a spring 62 exerts endpressure, asshown in Fig. 3.

moving downwardly, from dotted line position in Fig. 4, the'gauge arms35, intocontact with the counter f ofthe lasted shoe'to properlylocate-the position of the heel seat portionIf of the shoe relative tothe .heel plate holder -b. The operator then opens the Valve it bymoving-lever H to dotted line position, causing fluid pressure to enterthe cylinder 4, thereby actuating the piston therein and forcing theplunger 6 associated .therewith and the plate holder b downwardly tocause the prOn'g'sfiS of the heel seat plate H'topenetrate the heel seatmaterial of the s'hoe po'sitioned therebelow, which prongs. are clinchedby .coming'into'contact with the heel surface of the last upon which"the shoe F'is lasted. After the 7 plate applyingand securing-operation,the operator closes theval've l0, and the fluid pressure within thecylinder-is exhausted'due to. the spring within the cylindermovin'g' theplungerand'plate holder to its uppermosti'position,minustheheel seatplate H. lifter the'heel seat plate seating dent that the severalsuccessive steps or operaoperation, the operator releases foot pedal,and the gauge arms are automatically elevated to their uppermostposition, as shown in dotted lines in Fig. 4. The lasted shoe with theheel seat plate H applied thereto is then removed from the head It ofsupport 15.

From the foregoing description, it will be evitions of insertingfasteners and forming the heel area of a sole are carried out on asingle machine and the shoe is then ready to have a heel rigidlyattached to the heel seat area thereof.

From the foregoing description, it is also ap-- parent that Ipermanently fasten the heel attaching plate to the prepared heel seat ofthe sole under suitable pressure. and finally form the heel seat area ofthe sole for the mounting of a heel thereto, as well as holding thecounter of the shoe from spreading while pressure is being applied forattaching the plate to the heel seat of the 7 shoe.

While I have shown and described, in detail, one form of machine, itwill be observed that the shoe gauging device associated therewith for'able retaining means on the holder for holding the plate against theholder and means for actuating the ram to force the prongs of the platethrough the heel seat material of the shoe for locking the plate againstdisplacement on the heel seat of the shoe.
